The "DNS server not responding" error message in Windows 10 is familiar to many users whose workflow is suddenly interrupted by a lost internet connection. This is a critical error that blocks access to web resources because the computer cannot resolve domain names into understandable IP addresses. This problem is often accompanied by constant Wi-Fi connection drops, making it impossible not only to work but also to stream video or play online games.
The reasons for this operating system behavior may be hidden in software failures of Windows itself, as well as in incorrect operation of the router or provider. DNS failures Often occur after updating network card drivers, changing router configuration, or a virus attack. Understanding the nature of the error is the first step to successfully restoring a stable connection to the global network.
In this article, we'll cover proven action algorithms that will help you diagnose and fix the problem yourself. We won't use complex technical terms without explanation, but will instead walk you through every step, from a simple service restart to in-depth network protocol configuration. Careful adherence to instructions will allow you to restore your internet connection in a matter of minutes.
Primary diagnostics and equipment testing
Before delving into complex operating system settings, it's important to rule out basic hardware failures. Often, the cause lies in a simple router freeze, which stops correctly processing requests from connected devices. Rebooting network equipment Solves over 60% of all connection problems by clearing the temporary error buffer.
Unplug the router, wait at least 15-20 seconds, and then plug it back in. Wait for the device to fully boot up and for all the indicator lights to light up. If the "DNS server not responding" error persists in Windows 10, check the cables and WiFi signal strength on other devices.
⚠️ Attention: If the problem occurs only on one computer, and other devices are working normally, then the problem is localized in the Windows settings or the network card of this PC.
It's also worth checking whether Airplane Mode is enabled or whether the WiFi adapter is disabled by software. Sometimes users accidentally block the network interface by pressing the function keys on the laptop keyboard. Make sure the network card driver is installed correctly and the device is visible in Device Manager.
Reset network settings and DNS cache
The Windows 10 operating system stores DNS query information in a special cache to speed up performance. Over time, this cache can become full or corrupted, leading to name resolution errors. Forcefully resetting the accumulated data is one of the most effective solutions.
To perform this operation, you must launch the command prompt as an administrator. Right-click the Start button and select the appropriate menu item. In the window that opens, enter the command to clear the cache and reset the TCP/IP stack.
ipconfig /flushdnsipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
After entering each command, press Enter and wait for the message about successful execution. Command netsh winsock reset This is especially important because it resets the Windows socket directory, which is often damaged when installing third-party antivirus software or VPN clients.
☑️ Network Reset Checklist
After completing all the steps, be sure to restart your computer. The system will apply the new settings, and the "DNS server is not responding" error should disappear. If the problem returns immediately after rebooting, it's possible that your static IP address settings are the issue.
Configuring DNS server addresses manually
By default, Windows 10 obtains DNS server addresses automatically from your ISP. However, ISP servers are often unstable or block access to certain resources. Replacing them with public and reliable servers from Google or Cloudflare solves the problem in most cases.
To change the settings, go to Control Panel → Network and Internet → Network and Sharing CenterClick on the name of your connection (Ethernet or WiFi), then select "Properties." Find the item in the list. Internet Protocol version 4 (TCP/IPv4) and open its properties.
- 🌐 Select the "Use the following DNS server addresses" option.
- 🔢 In the Preferred DNS Server field, enter
8.8.8.8(Google). - 🔢 In the "Alternate DNS server" field, enter
1.1.1.1(Cloudflare). - ✅ Click "OK" and close all settings windows.
Using alternative DNS not only speeds up system response but also improves security, as major DNS providers often have built-in protection against phishing sites. If the internet works after changing the addresses, then the problem was with your provider's servers.
In some cases, you may need to disable IPv6 if it conflicts with your network equipment. To do this, simply uncheck the box in the connection properties. Internet Protocol version 6 (TCP/IPv6)This action is safe and often helps stabilize the connection.
Updating and reinstalling network adapter drivers
Outdated or corrupted network card drivers are a common cause of WiFi crashes or DNS server unresponsiveness. This is especially true after major Windows 10 updates, when the older driver version becomes incompatible with new system libraries.
Don't rely solely on the automatic driver search in Device Manager, as Windows often reports that "the best drivers are already installed." It's best to download the latest driver from the official website of your laptop or motherboard manufacturer.
| Manufacturer | Where to look for the driver | Device type |
|---|---|---|
| Realtek | Realtek official website | WiFi / Ethernet |
| Intel | Intel Download Center | WiFi (Intel Wireless) |
| TP-Link | TP-Link support site | USB adapters |
| Asus | Asus Support Section | Laptops / Boards |
Before installing a new driver, we recommend completely uninstalling the old one. In Device Manager, find your network adapter, right-click it, and select "Uninstall device." Be sure to check "Delete the driver software for this device," if available.
After uninstalling the driver, the network connection will disappear. Don't worry, this is normal. Now install the latest driver you downloaded earlier and restart your computer. The system should detect the hardware correctly, and the DNS error will disappear.
What should I do if I can't access the driver website?
If the internet doesn't work anywhere, download the driver on another device (a friend's phone or PC), transfer it to a flash drive, and install it on the problematic computer.
The impact of antiviruses and firewalls
Third-party antivirus programs often have their own network protection modules and firewalls that can mistakenly block DNS requests, deeming them suspicious. This is a common issue after updating the antivirus signature database or the antivirus itself.
Try temporarily disabling your antivirus's real-time protection and firewall. If this resolves the "DNS server not responding" error, the issue lies with your security settings. You'll need to either reinstall your antivirus or add an exception for Windows system processes.
⚠️ Important: Don't leave your computer without antivirus protection for long periods of time. After scanning, immediately re-enable protection or configure exclusions correctly.
It's also worth checking the built-in Windows firewall. Go to Control Panel → Windows Defender Firewall and select "Restore Defaults." This will reset all rules that may have been changed by viruses or user error.
If you're using a VPN or proxy, they could also be the cause. Disable your VPN and ensure that the proxy settings (Settings → Network & Internet → Proxy Server) are unchecked to use a proxy for your local network.
Resetting TCP/IP settings and working with the registry
In the most severe cases, when standard methods fail, a deep reset of network settings is required via the registry or special commands. Registry errors related to LSP (Layered Service Provider) protocols can completely paralyze the Windows 10 network stack.
Run the command netsh int ip reset in the command prompt as an administrator. This command overwrites the registry keys used by the TCP/IP protocol, returning them to the state they were in immediately after installing the operating system.
You can also use the built-in Windows troubleshooter. Go to Settings → Update & Security → Troubleshoot → Additional troubleshootersSelect "Network Adapter" and run the tool. The system will automatically attempt to find and fix configuration errors.
If this doesn't help, check your DNS Client service. Click Win + R, enter services.mscFind the DNS Client service in the list, make sure its startup type is set to "Automatic" and that it is running. If it is stopped, start it.
Frequently Asked Questions (FAQ)
Why does the DNS error only appear on one device on the network?
This indicates that the problem is localized in the settings of this specific device (computer or smartphone). Most likely, the static IP addresses are incorrect, the network card driver is outdated, or specific software is blocking the connection. The router or ISP have nothing to do with it.
Can a virus cause the "DNS server not responding" error?
Yes, many viruses and Trojans modify system hosts files or DNS settings to redirect user traffic to fraudulent websites. Be sure to run a full system scan using an antivirus and the Malwarebytes utility.
How can I check if my ISP's DNS server is working?
You can use online services to check DNS availability or simply ping the address. In the command line, enter ping 8.8.8.8If you can ping but can't open websites by name, the problem is definitely with DNS.
Should I change my DNS if my internet is slow?
Yes, changing your DNS to faster servers (such as Google or Cloudflare) can often speed up page loading by reducing the time it takes to look up the website address. This won't speed up file downloads, but it will improve browser responsiveness.
